上海市农科院土肥所微量元素组等,研制了葡萄专用营养液,也称葡萄素。供试配方:葡萄素1号:硼、钾两个元素为主体,占总有效成分80％。原液总浓度为12％,呈酸性。还含有其它7种螯合态微量营养元素;葡萄素2号:钴、钾、(金朋)为主体,占总有效成分75％。原液总浓度为13％,呈酸性。还含有其它8种螯合态微量营养元素。试材为“巨峰”,定植三年的幼龄树,作三个处理:①对照(喷清水);②配方1号;③配方2号。每处理32棵,随机
Shanghai Academy of Agricultural Sciences Soil and Fertilizer Group of trace elements, developed a grape-specific nutrient solution, also known as grape particles. Test formula: grape prime 1: boron, potassium two elements as the main body, accounting for 80% of the total active ingredients. The total concentration of stock solution was 12%, acidic. Also contains other seven kinds of chelated micronutrients; grape prime 2: cobalt, potassium, (Jinpeng) as the main body, accounting for 75% of the total active ingredients. The total concentration of stock solution was 13%, acidic. It also contains 8 other chelated micronutrients. Test material for the “Jufeng”, three-year-old young tree planting, for three treatment: ① control (spray water); ② Formula No. 1; Each processing 32, random
